| two cells are attached by a common membrane. in cell A, there is a sugar concentration of 0.5% and a starch concentration of 0.4%. in cell B there is a sugar concentration of 0.6% and no starch. sugar can pass through the membrane, but the starch cannot. assume that all other solutes are found in equal concentration within the 2 cells. use a simple diagram and a brief explanation to show: a) in what direction the sugar will move? b) in what direction osmosis will occur?
